No pics of his trainwreck but it is fire, we had a 10/10 germ rate, and every female was crazy, three of the 10 were very similar to the legit arcata cut we held, 1/10 was pure fire, we kept her and Dumped the original arcata cut, they are the exact same taste wise, but docs has better bag appeal, more trichs and is a bit more potent, cerebral highs are the same but the cut we kept had a better body high, the other 6 phenos were excellent too, just not like the keeper or other 3, but all had crazy trich production on lime green buds, light light brown hairs and reek of trainwreck, which to me has the most recognizable smell and taste in all of cannabis. I think of the 10 we had one that didn't have a strong pronounced trainwreck aroma and taste. The other 9 were all crazy. All very easy to get rid of b/c of bag appeal, aroma, and trich production. Overall the Chem 4 and cheese are very similar to the trainwreck, but if I had one recommendation of his strains besides the chem, sour, og, bubba og, and katsu bubba it would be the cheese, were at day 32 of our last bean, the pack was picked up 4 or so years ago so I wasn't sure if it would pop or if I would get a bad pheno, but after looking at and smelling her, I remembered we didn't have 1 bad cheese pheno of 9 beans so why would this lady be any different , and true to form she had a amazing cheese berry smell, perfect structure, literally no training or lst needed, just watch her grow, thin leaves, perfect branching and structure allow light to practically every bud on her, excellent yielder of blueberry cheese buds early in cure to straight cheese with a very light blueberry undertone after 1 month in the jar, for being sativa Dom, the cheese has an excellent all around high and amazing taste. And I think doc should reverse the cheese and pair her with the katsu.
